The first cable I received was DOA (unable to read or write data). Monoprice promptly sent a replacement at no cost to me, and that one works perfectly. I was able to attain the rated speeds on an external USB 3.1 SSD rated for 550 MB/s read and 500 MB/s write.

Works well. Cord is a bit thick, but that also means it's not going to break any time soon. Connector is a little big, but that makes no difference to function.Got it to use as a charge cable for my macbook pro, and it charges it perfectly well.

Love the look and quality feel of this cable. It's sturdy feeling and has reinforced ends. I don't see myself having any problems coming from shorts near the ends. For the price and quality you just can't beat them.

I hoped this would be a long USB-C cable that would allow my Pixel XL phone to charge rapidly from the charger that came with the phone, and the cable meets the criteria. It's a little stiffer than I'd like, but otherwise it's fine. I would recommend the cable.

Cable doesn't seat correctly in charging ports and devices, comes out while charging. Have woke up several times in the a.m. with an uncharged device. Which stinks because the cable is very rigid in comparison with others that I own
